ockbros + Durable 4 Color Bicycle Bell Bicycle Handlebar

Very difficult to fit (and a whole lot harder than the video in the description).
Took me about 20 minutes before I got the technique. Secret is to unscrew the bell head almost completely before trying to place one of the two metal bands). I finally managed by taking the bell head off completely for access (be careful if you do this that you don’t drop any of the internals, which are held in place by the central screw)

but….
Once fitted,
-it looks good,
– takes up little space on the handlebars,
– the ring is clear and
– there is very little to go wrong.

The difficulty in fitting is in part due to the use of a metal band, rather than the more common rubber attachments. But the pain this causes is worth it because the bell looks better once fitted.
